KNITTED FABRIC.

Specification of Letters Patent.

Patented Mar. 7, 1911.

Application filed April 8, 1909. Serial No. 488,543.

To all 'whom it may concern:

Be it known that I, ROBERT WV; SCOTT, a citizen of the United States,residing in Leeds Point, Atlantic county, New Jersey, have inventedcertain Improvements in Knitted Fabrics, of which the following is aspecification.

My invention relates to knitted fabrics Icomposed in part of ribbed weband in part tionable because a laterally displaced stitch does notpresent itself in the best position for the entrance of the needle towhich it is to he transferred.

The object ofmy present. invention has therefore been to overcome thisobjection in effecting such doubling transfers and at theV same time tomake a less abrupt change in the width of the .web at the point wherethe Wider web joins the narrower web.

In the accompanying drawings-Figure 1 is an exaggerated view of a pieceof Web knitted in accordance with my invention, in which a change iseffected from two-and-two ribbed web to plain web having a lesser numberof wales; Fig. 2 is an exaggerated view ofa piece of web in which changeis effected in accordance with my invention from a one-and-one ribbedWeb to plain web having a lesser number of wales;A Figs. ,3, 4; and 5are diagrammatic representations of the different dispositions of theneedles resorted to in knitting the web shown in Fig.v l, and Figs. 6, 7and 8 are diagrammatic representations of the different dispositions of[the needles resorted to in knit-tingV the web {f sh'own in Fig. 2.

Myinventioncanbe practiced upon any I V type of rib knitting machineprovided-With means for shogging the needles of one set 'in respect tothose of the other set so as for transferring stitches from needles ofone set to needles`of the other set, and with means for independentcontrol of the needles in the manner hereinafter set forth.

Usually my invention will be practiced in' connection with a circularrib knitting machine having the needles for. producing plain webcontained in the cylinder and the ribbing needles contained in the dial,hence, for convenience, I will, in my specification and claims, refer tothe plain web needles as cylinder7 needles and to the ribbing needles asdial needles, without, however, intending thereby vto limit myself to amachine of this type.

As 'an instance of a machine which, without much change is adapted forthe carrying out of my present invent-ion l may refer to that formingthe subject of my Letters Patent No. 834,763, dated October 30th, 1906.

The main difference between my present invention and previous inventionsof its with the standing Wale but a subsequently produced stitch, theobject being to permit the stitch which is actually transferred to bedrawn out straight over the receiving needle instead of being pulleddiagonally across the same, as -it must be when the transferred stitchis the shogged stitch.

In carrying out my present invention one or more, and preferably aplurality, of stitches are formed upon the shogged dial needles whilethe same occupy their new relation to the cylinder needles and beforeeffecting the transfer ofthe stitches from the dial needles to thecylinder needles, and in effecting the transfer the dial needles arepreferably projected to such an extent as to draw into line' withthereceiving needles the stitches of the course preceding that actuallycarried by said dial needles, both the preceding stitches and those castfrom the dial needles being caught by the receiving cylinder needleswhen said dial needles are retired, this having been found in practiceto be the best 'method of effecting the transfer, valthough in carryingout my invention it is not absolutely necessary to resort to thismethod, as but one course vof ribbed web may be formed upon the needleswhen they occupy their new relations, the stitches upon the dial'needlesbeing transferred vto v t b, c and By preference, ltwo of each of thereceiving cylinder needles. In either case the stitch to be' transferredwill, on the projection of the dial needle be drawnout directly over thereceiving `cylinder needle, there being no tendency to lateraldeflection vof said transferred stitch, because the stitches upon thecylinder needles on each side of the dialneedle-exercise 'substantiallythe same. degree of lateral. pull-fuponthe dial needle stitch.

In Fig. Laf'and bf represent the standing Wales which continuethroughout both the ribbed and plain webs, mf represent Wales which arerib wales in theribbedweb landplain Wales in t'he plain Web, and 'y'repre--V sent wale'swhich appear only lin the ribbed y web, the Walebbeing the same throughout, the rib Wale y being doubled intothestanding Wale a., and the rib Wale beingjdoubled into a freshly startedyplain web Wale 0'.'

In producing the two-and-two ribbed portions of this web the needles aredisposed as shown in Fig. 3, the web being produced upon the cylinderneedles aand b, and upon the intervening dial .needles :c andy, emptyand inactive cylinder needles c 4being interposed between lthedialneedles m andy'of each pair. l

The first step in the transfer operation'is to shog the needlesw and yinto line respectively with' the needles c and a, as .shown in Fig. 4,and two independent and interlocked ribbed Webs are then produced, Y,one a one-V and-one rib upon the needles and. (L, and. the other atWo-and-one rib, upon the needles these independent courses'are thusknitted, and the stitches upon the needles y as Well as the stitches ofthe precedingcourse are then transferred to the needles a, and the likestitches ,are transferred from the needles zu, to the'needles c, th'eneedles and gj being lthen retired from action and plain Web knittedupon'the cylinder as shown in Fig. 5.

. In the web shown in Fig. l', m2 and y2 represent the stitches upon theneedles .and gf at the time they are"shogged, w3 and 'f1/f3 stitches ofthe frstcourse knitted upon the needles a, '22, and c,

needles and g/ in their new relation, m4 and y* stitches ofthesecondcourse produced upon said needles w, y, in such new relation,

and c2, c3, a2, a3 and b2, b3 respectively the.

first and Second stitches formed upon the needles c, a and b in the newrelation, both stitches w3 and being transferred to the needles'c, andboth stitches ya and ybeing transferred to the needles a preparatory toAthe productionof plain Web. In this Web a thirty-threeandfone-thirdper-cent. doubling is effected, that is to say the'ribbed web hasthirty-three-and-one-third per y cent. more Wales than the plainweb.` Y

`In the web shown inv Fig.`2 va somewhat similar method of transfer isadopted in connection with a web in which change is effected from aone-and-one ribbed web to a plain web. In this web a and b represent thestanding wales which continue through- 'out both the ribbed and plainwebs, and aj and y the wales which'appear only in the lribbed web, thewales w being. doubled into the standing wales a and the Wales y beingdoubled into the standing wales 'b'. In producing this'web the dialneedles primarily `alternate in regular order. With the'cylinderneedles, as shownin Fig. 6, and ordinary one-and--one'ribbed webis'produced upon" the needles While they are in such relation.

The first step in the transfer operationis to shog the' dialneedles, sothat the needles a' will be in line with the cylinder needles a,

and the needles y'will be in line With the cylinder needles b, as shownin Fig. 7 and two independent and interlo'clred ribbed webs are thenproduced,.a course of one-andoneribbed web being first knitted upon theneedles 'b and a", and a course of one-and-one ribbedl web being thenVknitted uponA the needlesv aand y, as shown in Fig. A7, each of thesecourses being then, `byjpreference, followed byl a second course, afterwhich, the

needle stitches and those just preceding them l are transferredV fromthe needles. a: to the needles a, and from the needles y to the needlesb, the needles and g/ being then retired from 'action and plainWebbe'ing prof' duced upon the cylinder needles and as indicated in-Fig. v8. This produces. a Web` in which there is a one-hundred percent.

doubling, there being` twice as many wales in -the ribbed web asin theplain web. In Fig.

2 the stitches are'designate'd in the same manner as in Fig. l.

-' In both of he fabrics which I have showin the stitches transferredfrom the dial to the cylinder needles are subseand describe quent 1 tothe laterally displaced .stitches caused bythe shoggingvof the dialneedles and each transfer is 'what I term a straight 1 transfer causedby direct 'outward movement of the transfer needle" over-fthe receivingneedle` instead of a doubling transfer"effectl 4 ed by acompound.movementfofthe transfer needle which sl1 'ogs. or `laterally'deflectfsa ceiving needle. {In'bo'th of the fabricsshown and described,m orec ver',lthev changefroln one'character of'web yto, the othersiseffected through the medium vof an` intermediate Web'-v of a`characterdiiferent from that-'of either "5 is eh'ected'- through thelintervention'v of 'twd and in the web shown in Fig. 2 change fromone-and-one ribbed web to plain web is ef' `fected throughthe'intervention of two independent one-andone ribbed webs. By reason ofthe plurality ofcourses of stitches contained in the intervening web,the reduction in the width or diameter of the web is effected lessabruptly than when the shogged stitches are directly transferred.
